#2971:

• Added cube, cuberoot, absolute and analytical quotient to IntervalInterpreter
• Extended the IsCompatible method in IntervalInterpreter (removed power, root because not implemented in DerivativeCalculator
• Added checks for known symbols at InteractiveSymbolicDataAnalysisSolutionSimplifierView and SymbolicRegressionSolution
